On more recent distros (FC9/10) SELinux is enabled by default. Rolling a
policy specifically for an untrusted bottle would severely limit the
damage it could do. It could restrict all unnecessary read/write/execute
access outside of the ~/.wine folder for wineserver and the program.
I see your point though, since none of the aforementioned security
precautions are commonplace or specifically targeted to wine.
